Aspartame

(3S)-3-amino-4-[[(2S)-1-methoxy-1-oxo-3-phenylpropan-2-yl]amino]-4-oxobutanoic acid

C14H18N2O5 (294.1215658)


Aspartame is the name for an artificial, non-carbohydrate sweetener, aspartyl-phenylalanine-1-methyl ester; i.e., the methyl ester of the dipeptide of the amino acids aspartic acid and phenylalanine. It is marketed under a number of trademark names, such as Equal, and Canderel, and is an ingredient of approximately 6,000 consumer foods and beverages sold worldwide. It is commonly used in diet soft drinks, and is often provided as a table condiment. It is also used in some brands of chewable vitamin supplements. In the European Union, it is also known under the E number (additive code) E951. Aspartame is also one of the sugar substitutes used by diabetics. Upon ingestion, aspartame breaks down into several constituent chemicals, including the naturally-occurring essential amino acid phenylalanine which is a health hazard to the few people born with phenylketonuria, a congenital inability to process phenylalanine. Aspartic acid is an amino acid commonly found in foods. Approximately 40\\\% of aspartame (by mass) is broken down into aspartic acid. Because aspartame is metabolized and absorbed very quickly (unlike aspartic acid-containing proteins in foods), it is known that aspartame could spike blood plasma levels of aspartate. Aspartic acid is in a class of chemicals known as excitotoxins. Abnormally high levels of excitotoxins have been shown in hundreds of animals studies to cause damage to areas of the brain unprotected by the blood-brain barrier and a variety of chronic diseases arising out of this neurotoxicity. Compd. with 100 times the sweetness of sucrose. Artificial sweetener permitted in foods in EU at 300-5500 ppmand is also permitted in USA.

gamma-Glutamylphenylalanine

(2S)-2-Amino-4-{[(1S)-1-carboxy-2-phenylethyl]carbamoyl}butanoic acid

C14H18N2O5 (294.1215658)


gamma-Glutamylphenylalanine is a dipeptide composed of gamma-glutamate and phenylalanine, and is a proteolytic breakdown product of larger proteins. It is probably formed by transpeptidation between glutathione and the corresponding amino acid, catalyzed by gamma-glutamyl transpeptidase (PMID: 237763). gamma-Glutamylphenylalanine belongs to the family of N-acyl-alpha amino acids and derivatives. These are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. gamma-Glutamylphenylalanine is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. It can be detected in the urine of patients with phenylketonuria, which is a human genetic disorder due to the lack of phenylalanine hydroxylase to metabolize phenylalanine to tyrosine (Wikipedia). gamma-Glutamylphenylalanine is found in adzuki bean, onion (Allium cepa), garlic (Allium sativum), and soybean. γ-Glu-Phe (γ-Glutamylphenylalanine) is synthesized by Bacillus amyloliquefaciens (GBA) and Aspergillus oryzae (GAO). γ-Glu-Phe or the post-enzymatic reaction mixture enhances the umami intensity of commercial soy sauce and model chicken broth[1]. γ-Glu-Phe (γ-Glutamylphenylalanine) is synthesized by Bacillus amyloliquefaciens (GBA) and Aspergillus oryzae (GAO). γ-Glu-Phe or the post-enzymatic reaction mixture enhances the umami intensity of commercial soy sauce and model chicken broth[1].
